EYEGLASSES.

SPECIFICATION forming part of Letters Patent No. 425,595, dated April 15, 1890. Application filed July 24, 1889. Serial No. 318,630. (No model.)

To all whom it may concern:

Be it known that 1, JOHN CURRIN, a citizen of the United States, and a resident of Southbridge, in the county of Worcester and State of Massachusetts, have invented a new and useful Improvement in Eyeglasses, set forth in the annexed specification, which contains a full, clear, and exact description of my invention, accompanied by drawings, forming a part of the same, and showing an eyeglass embodying the essential features of my invention, and in which Figure 1 represents a front view of the eyeglass. Fig. 2 is a top view. Fig. 3 is a top view with the nose-guard springs removed. Fig. 4 represents an elevation of an eyeglass, showing a modified form of nose guard spring. Fig. 5 is a sectional View of one of the nose-guards on line X X, Fig. 6. Fig. 6 represents a rear view of one of the noseguards with the nose-guard spring removed; and Fig. 7 is a transverse sectional view of one of the nose-guards on line Y Y, Fig. 6.

Similar letters refer to similar parts in th several views.

My invention relates to that class of eyeglasses which are attached to the nose by means of nose-guards connected with the frame of the eyeglass by springs whose tension serves to press the nose-guards against the sides of the nose.

In the accompanying drawings, A A denote the eye-wires; B B, the lenses.

0 O are lugs projecting inwardly from the eye-wires A A.

D denotes the bow-spring.

E are the nose-guards attached to the free ends of the nose-guard springs FF. The fixed ends of the nose-guard springs are attached to the lugs O O, and. each of the springs is carried from the lug to which it is attached over the bow-spring D, and parallel with it to the central portion of the bowspring. The nose-guard spring is then returned at G parallel with the bow-spring, and having its free end H. turned upwardly, and entering a mortise I in the metallic band J of the nose-guard E. The nose-guards are formed of the metallic strips J, having their longest sides turned over at K to partially inclose and hold the strips of cork, rubber, or other material suitable to rest against the sides of the nose. The free ends of the noseguard springs F F enter the mortises I I and are attached to the inner sides of the metallic strips J J.

As shown in Fig. l of the drawings, the nose-guard springs are returned upon themselves, forming a curved loop, as at L; but, if desired, the nose-guard spring can be made of two separate pieces in each spring, with the pieces fastened together at a a by screws,

rivets, or soldering. g

The construction of that part of the eyeglass comprising the eye-wires, lenses, and bow-spring is substantially the same as the eyeglasses now in common use; but I attach the nose-guards to separate and independent springs, allowing the glasses to be placed upon the nose without bringing any strain upon the bow-spring and consequent displacement of the lenses.

I do not herein claim the use of an independent spring to which the nose-guards are attached to be broadly new; but in the peculiar form of the nose-guard spring shown I am able to connect the nose-guard springs with the lugs to which the bow-spring is attached, bringing the strain of both bowspring and nose-guard, springs upon the same point of the frame, which can be made sufficiently heavy and strong at that point for the purpose; and I also secure a long section of the nose-guard spring to act upon the noseguards, the entire portion from the noseguards to the looped section L receiving the strain as the nose-guards are separated in placing the eyeglasses upon the nose. The sides K of the strips J are bent over to partially inclose and enter the sides of the strip M, which is preferably made of cork or a similar semi-elastic substance, and the sides K form acute angles with the strip M, which is compressed between the edges of the sides K K, forming a dovetailed joint, as shown in Fig. 7 of the drawings.

What I claim as my invention, and desire to secure by Letters Patent, is-=- The combination, with the eye-Wire's of a of attachment to said eye-wires, and then bepair of eyeglasses, ofi'nose-guard springs ating curved downward and in ward, substantached at one of their ends to the eye-wires tially as described. a

and carrying at their free ends nose guards, JOHN CURRIN. 5 said nose-guard springs extending from the Witnesses: eye-wires over the bow-spring and returning CHAS; D. MONROE,
